RE: Ncurses for mips

[Vivek]

Hi

After over-riding the cflagsm the config.log reports following entry

$ ./configure --prefix=/home/dvivek/test/ncurses --with-build-cc=gcc
--host=mips-linux --target=mips-linux --with-build-cflags=-O3 

However compilation still failed as the cross compiler flags are passed to
host compiler as is shown below. I thought only the flags specfied in
--with-build-cflags will be passed to host compiler.

What may go wrong ?

Thanks.

You need to override the configure script using --with-build-cflags.
>From "INSTALL":

     --with-build-cc=XXX
         If cross-compiling, specify a host C compiler, which is needed to
         compile a few utilities which generate source modules for ncurses.
         If you do not give this option, the configure script checks if the
         $BUILD_CC variable is set, and otherwise defaults to gcc or cc.

     --with-build-cflags=XXX
         If cross-compiling, specify the host C compiler-flags.  You might
need
         to do this if the target compiler has unusual flags which confuse
the
         host compiler.

     --with-build-cppflags=XXX
         If cross-compiling, specify the host C preprocessor-flags.  You
might
         need to do this if the target compiler has unusual flags which
confuse
         the host compiler.

     --with-build-ldflags=XXX
         If cross-compiling, specify the host linker-flags.  You might need
to
         do this if the target linker has unusual flags which confuse the
host
         compiler.

     --with-build-libs=XXX
         If cross-compiling, the host libraries.  You might need to do this
if
         the target environment requires unusual libraries.
